If the AH has a GRH then hold a reference to the sgid_attr inside the common struct. If the QP is modified with an AV that includes a GRH then also hold a reference to the sgid_attr inside the common struct. This informs the cache that the sgid_index is in-use so long as the AH or QP using it exists. This also means that all drivers can access the sgid_attr directly from the ah_attr instead of querying the cache during their UD post-send paths.
